quantum-computingFaster Qubit Readings Now Avoid Unwanted Energy State Changes
Nicholas Zobrist and colleagues at Google Quantum AI have developed a new approach to stabilising qubit transitions by incorporating an inductive shunt into transmon qubit design. This effectively removes dependence on offset charge. The ‘shunt’ functions as an alternative pathway for electrical current, bypassing sensitivity to fluctuating electrical charges that previously induced unwanted changes in the qubit’s state. These changes, known as measurement-induced state transitions or MIST, are akin to disturbing a delicate balancing act during observation. MIST arise because the measurement process itself introduces photons into the readout resonator, and a sufficient number of these photons can induce transitions to higher energy states in the qubit, corrupting the measurement outcome. By mitigating offset charge dependence, the inductive shunt allows dispersive readout, a technique for gently probing a quantum system to determine its properties, to function reliably without complex calibrations or large detunings between the qubit and its readout resonator. Offset charge refers to stray electric fields caused by imperfections in the materials and fabrication processes, which affect the qubit’s energy levels and introduce noise. Traditionally, these charges have been addressed through meticulous calibration procedures or by increasing the frequency separation between the qubit and the readout resonator, a technique known as detuning. However, detuning reduces the strength of the qubit-resonator coupling, potentially slowing down measurement speed and reducing signal quality. Inductive shunts suppress measurement-induced qubit state transitions through offset charge control An inductive shunt added directly to the transmon qubit proved key to stabilising measurements. The ‘shunt’ functions as an alternative pathway for electrical current, bypassing sensitivity to fluctuating electrical charges that previously induced unwanted changes in the qubit’s state.

quantum-computingQuantum Simulation Reveals How Disorder Drives System Thermalisation
Faisal Alam and colleagues at Phasecraft Ltd, in a collaboration between Phasecraft Ltd, Phasecraft Inc and Virginia Tech, observed the onset of ergodicity, the property of a system exploring all accessible states, using a two-dimensional disordered Heisenberg Floquet model simulated on IBM’s Nighthawk superconducting processor. The study probes ergodicity across multiple length scales using a new measure based on collision entropy, accessing system sizes previously intractable for classical computation. By analysing how ergodic behaviour emerges at different scales, the team reveal a hierarchical transition from subergodic to ergodic behaviour as Heisenberg coupling increases, and provide a new pathway for using digital quantum processors to study thermalisation phenomena. Emergent ergodicity and spatial hierarchy in a large-scale quantum system This breakthrough utilised IBM’s Nighthawk superconducting processor, a device employing transmon qubits fabricated using superconducting materials, enabling the probing of ergodicity, a system’s tendency to explore all accessible states, across multiple length scales. The Heisenberg model, a cornerstone of quantum magnetism, was chosen to represent interacting spins, and the ‘Floquet’ aspect introduces time-periodic driving, adding complexity and potentially enhancing ergodicity. A novel measure based on ‘collision entropy’ quantified the emergence of ergodic behaviour within spatial patches of the system, revealing a hierarchy where smaller regions become ergodic before larger ones. The concept of ergodicity is crucial in statistical mechanics, as it underpins the equivalence between time averages and ensemble averages, essential for predicting macroscopic properties from microscopic dynamics. Disordered systems, where imperfections or randomness are present, pose a particular challenge to establishing ergodicity, as localisation effects can hinder the exploration of the entire state space.

Schoelkopf View a PDF of the paper titled Rhenium as a material platform for long-lived transmon qubits, by Yanhao Wang and 4 other authors View PDF HTML (experimental) Abstract:Dielectric loss at the interfaces of superconducting films has long been recognized as limiting the performance of state-of-the-art superconducting circuits. Notably, the presence of a native oxide layer on the film is hypothesized to contribute to dielectric loss at the metal-air interface. Here, we explore rhenium as a candidate for the film, motivated by its remarkable property to suppress native oxide formation. We demonstrate rhenium on sapphire as a promising material platform for superconducting circuits through the realization of transmons with mean relaxation times $T_1$ up to 407 microseconds at 5 GHz. Our transmons are supplemented with a loss characterization study, in which we separate the dominant loss mechanisms and construct a loss budget that agrees with our $T_1$ measurements. Further characterization may establish rhenium as a leading candidate for maximizing decoherence time.

Starting from the Feynman-Kac formula, we convert each trajectory into a sequence of piecewise-constant one-body generators using stochastic Magnus expansions up to second order, and embed the resulting nonunitary slices into unitaries with a small ancilla overhead. This lifts the projector dynamics to a unitary evolution, enabling coherent circuit execution in the regime $\|\Omega \| \tau=O(1)$ and reducing the need for frequent mid-circuit measurement. We further derive an equivalent linear-combination-of-unitaries (LCU) form that yields system-only, shallower circuits by trading ancilla cost for additional trajectory sampling. Benchmarks on the Hubbard model verify the accuracy of the dilation and Magnus expansions classically and demonstrate multi-step executions on IBM quantum hardware.

Amorphous Al$_2$O$_3$ is widely used as a barrier material, but under irradiation, oxygen vacancy (V$_O$) defects are readily generated, introducing noise sources that accelerate qubit decoherence. We systematically investigate the structural characteristics and electronic impact of V$_O$ defects in amorphous Al$_2$O$_3$ using first-principles calculations and \textit{ab initio} molecular dynamics. Our results show that both the coordination environment and concentration of V$_O$s strongly influence electrical conductivity. In particular, two- and three-coordinated V$_O$s, unique to the amorphous structure, enhance conductivity more than conventional four-coordinated vacancies. Increasing V$_O$ concentration amplifies conductivity fluctuations, which we link to critical current noise in Josephson junctions. Using a noise model, we estimate that higher V$_O$ densities lead to shorter qubit coherence times. These findings provide insights for radiation-hard design of superconducting quantum devices.
